VALVE.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed October 19, 1908. Serial No. 158.449,

To all whom 'it may concer/rt:

Be it known that l, NioHoLks l. Entrna- THUM, a citizen ol the United States, and resident of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Valve, or' which the iollowing is a full, clear, and exact description.

The invention is an improved valve for flush tanks and is designed to provide a simple eiiective construction for the purpose, in which gaskets or other packing in connection with the working parts is dispensed with.

To this end the invention consists of the combination of a valve casing having a longitudinal here, an outlet opening and a slot near one end intersecting said bore, a valve having a stem of tubular construction intermediate its ends and slidahle in said bore, provided with a slot of less length than the slot of the casing and in register therewith, the valve stem further provided with inlet and outlet openings respectively leading into and out of the tubular portion of the stein, and a float-controlled arm pivoted to the valve casing and passing through both the slot of the casing and the slot oi' the valve stem, for seating the valve and moving it from its seat and bringing the outlet opening of the valve stem in register with the outlet opening of the valve casing.

Reference is to he had to the accompanying drawings forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a vertical central sectional view through the preferred form of my improved valve, showing the valve in seated position Eig. 2 is a similar sectional view showing the valve depressed and unseated; and Fig. 3 is a view of the valve looking in the direction of the arrow in 2 and partly in central vertical section.

The invention essentially consists of a valve casing 5, a valve 6 and a float-controlled arm or operating lever 7. The casing has a longitudinal here which is enlarged or counterhored at its lower or shank end to produce a valve sea of conical form, and at the opposite and upper end of the casing/'it has a slot 9 intersecting its bore. At the juncture of the body or upper portion of the casing and its shank a shoulder 10 is formed, and the said shank is externally threaded both for receiving a jam-nut 11 and a coupf ling 12 for connecting it with the water supply pipe 13, th ain-nut serving to 1sind the flush tank 14; between it and the shoulder and torni water-tight connection hy ine-ans of suitable gaskets 15.

rFhe valve 5 is constructed with a relatively long stem, which is tubular intermediate its ends and has transverse slot 15, ahove the tubular portion, oi less length than the slot 9 in the casing and in register therewith. At the hottom of the tubular portion of the stem adjacent to the valve head are inlet openings 17, and similar outlet openings 18 are provided at the head of the tubular portion of the stem and are adapted to register with downwardly and outwardly-inclined outlet openings 19 in the valve casing, as shown in Eig. 3, when the valve is depressed and unseated. The float-controlled arm 7 passes through both the slot 9 ofthe casing and the slot 16 of the valve stem, and is pivotally connected to a hii'urcated arm 2O projecting upwardly and outwardly from the casing and integral or otherwise rigid therewith.

In the operation of the valve when thus applied to the flush tank, when the tank is iilled, the arm 7, under the action of the usual float, presses the valve firmly to its seat and cuts olf the water supply. TWhen the water runs out of the tank the arm 7 drops, unseating the valve and placing the inlet openings 17 in communication with the water supply, and the outlet openings 1S in register with the outlet openings 19 or' the casing. The water on passing out oi' the openings 19 is prevented from spattering over the sides oi the tank hy reason of the manner in which these openings are directed. As the water rises in the tank, the float-controlled arm gradually raises the valve to its seat, completely cutting oil the supply when the normal water level in the tank is reached.

Having thus described my invention, l claim as new` and desire to secure by Letters Patent:

1. rlhe combination of a valve casing havling a longitudinal hore, an outlet opening A and a slot near one end intersecting said hore, a valve having a stem of tuhular construction intermediate its ends and slidahle in said bore and provided with a slot of less length than the 'slot of the casing and in register therewith, said valve stem heing further provided with inlet and outlet openings respectively leading into and out of the tubular portion of the stem, and a float-controlled vided with inlet and outlet openings respecl tions thereof7 a vlioat-controlled arm passing through the slot of the easing and connected with the stein of the valve, operable When moved to extreme positions to respectively l seat the valve and to unseat the valve and bring the outlet opening of the valve stem in register with the outlet opening of the valve easing.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

arm ivoted to the valve easing and extending t rough both the slot of the casing and the slot of the valve stem, for seating the valve and moving it from its seat and bringing the outlet opening of the valve stem in register with the outlet opening of the valve I easing.

2. The combination of a valve casing having a bore and a slot intersecting the upper portion of the bore, said easing provided with an outlet opening in the side thereof below said slot, a valve having a stem slidable in the bore of the easing, with the intermediate portion of said Stem of tubular form and protively arranged at the upper and lower por-
